MILK SUBSTITUTES:Any plant-based milk or traditional milk will work in this recipe. I prefer oat milk because it is the creamiest. A NOTE ON CHOCOLATE:I used an 85% dark chocolate bar in the recipe, I prefer super dark chocolate but you are welcome to use the chocolate that you prefer.Chocolate chips will work but they will take longer to melt and they don't tend to produce as creamy a texture.
